PACKING GLAND.

Specification of Letters Patent. Patented Jan, 24,, 1922 Originalapplication flled March 29, 1920, Serial No. 369,762. Divided and thisapplication filed May 17,

1920. Serial No. 382,139.

To all whom it may concern:

Be it known that I, LANsorrB. JOYNER, a citizen of the United States,and a resident of Washington, parish of St. Landry, and State ofLouisiana, have invented a new and useful Improvement in Packing-Glands,of which the following is a full, clear, and exact description.

My invention relates to improvements in packing glands, and it consistsin the combinations, constructions, and arrangements herein describedand claimed.

An object of my, invention is to provide a novel form of packing glandthat is particularly adapted for application to a cylinder of aninternal combustion engine.

A further object of my invention is to provide an effective andpractical means for effecting a tight connection between a cylinder andthe parts associated therewith in such a manner as to permit suchassociated parts to satisfactorily perform the functions for whichdesigned.

A further object ofiny invention is to provide adevice of the typedescribed that is strong and durable in construction and not likely toget out of order easily.

Other objects and advantages will appear in the following specification,and the novel features of the invention will be particularly pointed outin the appended claims.

This ap lication is a division of the application or atent on internalcombustion engine, filed by me March 29, 1920, Serial No. 369,762.

My invention is illustrated in the accompanying drawings, forming partof this application, in which- Fig. 1 is a side view of the device asoperatively applied,

Fig. 2 is a horizontal sectional view of the mechanism shown in Fig. 1.

In carrying out my invention, I make use of a cylinder, a fragmentaryportion of which is denoted by 1 in the drawings. The cylinder 1 isprovided with a cylinder head 2 which is secured thereto in an ordinarymanner as by means of bolts 3. A piston rod 4 is arranged to move in itsreciprocation through a central opening 5 provided in the cylinder head2. The cylinder head 2 is formed with a central outwardly extendingintegral extension 7 which surrounds the central opening5. The integralextension 7 has an outwardly extending annular rib or flange 8 at itsouter end.

v flange 8.

der head 2 and rigidly secured thereto by any suitable means, as bywelding.

I then provide a pair of Semi-cylindrical members 9 and 10, which havesimilar lateral lugs 11 and 12 which aiford a means for clamping themembers 9 and 10 together about the piston rod 4, bolts 13 being used toaccomplish this result.

In Fig. 2 of the drawings, the construction of the member 9 is shownindetail. The following description of the member 9 applies also to themember 10, since these members are precisely identical.

The semi-cylindrical member 9 is formed with internal semi-annularrecess 14, which is adapted to receive the annular rib or Additionalsemi-annular recesses 15 are provided in the inner wall of the member 9intermediate its length. A re- .cess 18 in the inner wall of the member9 extends inwardly from the outer end thereof, the wall of the recessbeing tapered at 21 as shown in the drawings. A plurality of relativelythin inner packing rings 16 are disposed about the piston rod 4 and aremaintained in position by an outer packing ring 17 which is disposedwithin the recess 15; The inner packing rings are preferably formed ofbrass or a like composition while the outer packing rings are preferablyformed of cast iron or the like.

A suitable packing 19 is disposed within the recess 18 about the pistonrod 4. This packing is compressed by means of a sleeve member 20, whichhas its tapered end portion 22 inserted within the recess 18, as shown.The sleeve 20 is formed with a flange 23 and is adjustably secured tothe members 9 and 10 by means of bolts 6. It will be noted that thepacking 19 can be compressed as desired by screwing the bolts 6 into themembers 9 and 10, thus moving the tapered end 22 of the sleeve 20inwardly.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. The semi-cylindricalmembers 9 and 10 are secured together by the bolts 13, thus maintainingthe packing rings and the packing about the pitson rod 4 in thepositions shown. in the drawings, while permitting a freereciprocating-movement of the latter. The device provides a strong anddurable means for effectively packing the connection of a cylinder orthe like and a movable portion, such as a piston rod, whereby the escapeof gas, steam, or the like, is prevented and the parts to which thedevice is applied are enabled to satisfactorily perform their normalfunctions.

It will be understood that the piston rod will in service be lubricatedin any suitable manner, no means foraccomplishing this object beingshown in the accompanying drawings. impregnated with a lubricant.

I claim:

1. The combination with a cylinder having a cylinder head formed with anoutwardly extending integral rib surrounding a central opening and apiston rod extending through said central opening, of a packing glandarranged to connect with said cylinder head, said packing gland beingformed with an annular recess adjacent one end thereof adapted toreceive said annular rib, whereby said packing gland is maintained inposition, an intermediate annular recess ada ted to receive an outerrelatively hard pac ing ring and a plurality of inner relatively softpacking rings arran ed concentrically therewith, a recess adjacent theother end of said packing gland adapted to The packing 19 may also beranged to extend'through said central open ing, ofa pacln'ng glandarranged to connect with said cylinder head, said'packing gland pickingdisposed v ing adjustably being formed of supplementary sections aformed with cooperatin semi-annular recesses in their inner walfiiadjacent one end thereof adapted to receive said annular rib, and withadditional cooperating semi-annular recesses in their inner wallscommunicating with said first named annular recesses, means for securingsaid sections together to maintain said packing gland in determinedposition relative said cylinder head, an

outer (packing ring disposed within said last name recesses, and aplurality of circumferentially alined inner Backing rings arrangedconcentrically wit said outer packing ring andhaving their inner wallsengaging the iston rod.
